At present,the hybridization of Differential Evolution with local search method confines to DE with a crossover based local search method.A novel differential evolution algorithm with best-individual based Local Search strategy is proposed.In LSDE,a normal distribution operator is introduced to automatically modify search length,and time-varying factors are introduced to modify the two parameters of DE.

针对目前差分进化与局部搜索相结合仅局限于基于交叉的局部搜索的方法，提出了一种基于最佳个体局部搜索策略的差分进化算法，并引入正态分布算子自动调整搜索步长和时变差分进化因子调整DE的两个参数。

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

关系数据库上的关键词检索已成为数据库和信息检索领域的研究热点之一现有数据库关键词检索系统可分为在线和离线两大类，它们都难以兼顾查询效率和效果：在线系统能够获得数据库最新结果，但速度较慢；离线系统使用预处理提高查询速度，但若数据库更新就要重新执行预处理。

In the chapter 5, during the optimization, the influence of search efficiency of choosing search variable is studied, and author proposes a kind of choice, which the positions of two exit points and the sagitta of the slip surface are taken as the search variable (the sagitta depends on the dynamic positions of two exit points of the slip surface), The examples show that the choice method decrease search region, improve the efficiency of searching, and has applying foreground.

在第五章中，探讨了搜索变量的选取对搜索效率的影响，对此作者提出以滑弧的两个端点位置以及它所组成的弓形高为搜索变量。实例表明，搜索变量的这种选取方法缩小了搜索范围，提高了搜索效率，有很好的应用前景。

The report points out, accompanying the fractionize of user demand and development, appeared to be aimed at the professional search of specific industry, the content of the search more essence of life is accurate, the search pays attention to the demand of the user more as a result, more individuation, search a result more structuralization.

报告指出，伴随着用户需求的细分和深入，出现了针对特定行业的专业搜索，搜索的内容更加精准，搜索结果更加注重用户的需求，更加个性化，搜索结果更加结构化。

Search Crawler Web search for a basic search procedures, it features based on the search application's basic framework.

Combining the advantages of fixed search pattern and spatial correlation search pattern,the algorithm employs the high search accuracy of DS and the high search speed of ARPS.It performs zero motion prejudging for immobile macroblocks between the two adjacent frames to reduce the computational complexity,and employs the spatial correlation of motion vectors to improve the quality of predicted motion vectors.

该算法利用DS算法搜索精度高和ARPS算法搜索速度快的特点，综合固定模式搜索和空间相关搜索两方面的优点，对于相邻两帧图像中的不变宏块采用零运动预先判断以减少算法的计算量，并利用运动矢量的空间一致性提高预测运动矢量的质量。
